The original OM-D E-M5 has had a great run since being announced roughly two years ago, but it's time for an upgrade. Accordingly, Olympus is taking the wraps off of the E-M5 Mark II, a Micro Four Thirds camera that aims to go head to head with the likes of Sony's recently released A7 II and other similar mirrorless shooters. Olympus says that the second-generation E-M5 isn't here to replace its flagship OM-D camera, the E-M1 -- though it very well could, at least on paper. And even though it is very similar in looks to its predecessor, the E-M5 Mark II brings enough internal changes to make it a worthy successor. For starters, it packs a redesigned 16-megapixel Live MOS sensor, coupled with a TruePic VII image processor, an upgraded 81-point autofocus system, a 40-megapixel high-res shot mode, a 3-inch (articulating) touchscreen and WiFi.
